I'm Tarik Perviz, a full-stack engineer in Sarajevo. I build products end to end at MasterBuild.ai, and ship my own on the side.
closed testing
A real-money prediction market. Users buy and sell YES/NO shares on future events at prices set by an automated market maker, and get paid out when markets resolve.
Full-stack: the fixed-product market maker, a double-entry ledger where balances are derived rather than stored, payment webhooks, realtime prices over websockets, and the AWS infrastructure behind it.
An AI-assisted support and engineering portal. Customers file cases on a shared timeline; a tenant-bound AI engine investigates with approved read-only tools and drafts replies that a human reviews before anything reaches the customer.
Full-stack across the .NET services, the custom MCP server, and the React app.
An AI autopilot for compliance. My part was the marketing site: an editorial design system with scroll-pinned storytelling sections and a careers area.
The first student-work marketplace in Bosnia and Herzegovina. Verified students find gigs and internships, clients post listings and hire, and trust is built without on-platform payments: identity vetting, double-blind reviews that unlock only when both sides submit, disputes, and moderation.
Built the whole thing, including realtime chat and the trust-and-safety machinery.

in development
An AI assistant for football coaching staff, in development with a professional club. Every coach on the staff gets an agent for their job, and drills are sketched on a 2D pitch from a text prompt, then edited the same way. The AI drafts, the coach decides.
